This study examined the relationships of perceived ethical leadership, workplace jealousy, and organizational citizenship behaviors directed at individuals and organizations. Survey responses were collected from 491 employee-coworker pairs from 33 hospitals in Taiwan. The employees provided assessments of their perceived ethical leadership and the workplace jealousy they experienced, while the coworkers provided information about the employees’ OCBI and OCBO. In the hypotheses testing, perceived ethical leadership was found to be negatively related to employees’ workplace jealousy and jealousy was negatively related (...) to their OCBI and OCBO. Workplace jealousy partially mediated the effect of ethical leadership on OCBI and OCBO. In addition, perceived ethical leadership was found to have a moderation effect on the jealousy-OCBI/ocbo relationship. This study contributes to the literature of ethical leadership as well as to the literature of OCB by relating workplace jealousy to OCB and by making sense of the effects of ethical leadership on OCB through the mediation of jealousy and through the moderation of ethical leadership on the jealousy-OCB relationship.

A two stage model was developed and tested to explain how ethical leadership relates to followers’ ethical judgment in an organizational context. Drawing on social learning theory, ethical leadership was hypothesized to promote followers’ self-leadership focused on ethics. It was found that followers’ perceived accountability fully accounts for this relationship. In stage two, the relationship between self-leadership focused on ethics and moral judgment in a dual decision-making system was described and tested. Self-leadership focused on ethics was only related to moral (...) judgment when followers use active judgment as opposed to their intuition. This provides support that a deliberate application of self-leadership focused on ethics leads to higher moral judgment. Theoretical and practical implications as well as future research opportunities are discussed. (shrink)

In this paper, we investigate the trust-based mechanisms underlying the relationship between ethical leadership and followers’ organisational citizenship behaviours (OCBs). Based on three-wave survey data obtained from 184 employees and their supervisors, we find that ethical leadership leads to higher levels of both affective and cognitive trust. In addition, we find support for a three-path mediational model, where cognitive trust and affective trust, in turn, mediate the relationship between ethical leadership and follower OCBs. That is to say, we found that (...) ethical leadership leads to the development of cognitive trust, which subsequently influences the development of affective trust. Affective trust, in turn, induces followers to exhibit OCBs as a means of reciprocating the leader’s favourable behaviour. Our findings suggest that both affective and cognitive trust plays an important role in the social exchange processes that underlie the relationship between ethical leadership and the discretionary behaviour of followers.

We develop and test a process model demonstrating how leader charisma and constructive and destructive forms of narcissism interact to influence follower psychological empowerment and moral identity, using survey data from 667 direct reports of leaders from 13 different industries. Study results revealed that leader narcissism moderates the relationship between leader charisma and follower psychological empowerment such that when leaders possess a more constructive and less destructive narcissistic personality, their charisma has a stronger positive relationship with follower psychological empowerment. Study (...) results also revealed that follower psychological empowerment mediates the differential interactive effects of leader charisma and constructive and destructive narcissism on follower moral identity. Implications of these results for future theory development, research, and practice are discussed. (shrink)

According to social learning theory, we explored the relation between ethical leadership and knowledge hiding. We developed a moderated mediation model of the psychological safety linking ethical leadership and knowledge hiding. Surveying 436 employees in 78 teams, we found that ethical leadership was negatively related to knowledge hiding, and that this relation was mediated by psychological safety. We further found that the effect of ethical leadership on knowledge hiding was contingent on a mastery climate. Finally, theoretical and practical implications were (...) discussed for leadership and knowledge management. (shrink)

The present study examined the direct and indirect (via relational social capital) relationships between supervisors’ ethical leadership and knowledge hiding. It also tested the moderating role of instrumental thinking in the relationship between supervisors’ ethical leadership and knowledge hiding and the relationship between supervisors’ ethical leadership and relational social capital. Data were collected from 245 employees in different firms spanning different manufacturing and service sectors. The results showed that supervisors’ ethical leadership was negatively related to knowledge hiding, both directly and (...) via relational social capital. The results revealed that instrumental thinking moderated the positive relationship between supervisors’ ethical leadership and relational social capital, such that the relationship was weak when instrumental thinking was high. The results also showed that instrumental thinking moderated both direct and indirect relationships between supervisors’ ethical leadership and knowledge hiding, such that the relationships were weak when instrumental thinking was high. The study carries important practical implications for managers concerned about the destructive consequences of knowledge hiding. (shrink)
